FCM Revenue Grade Split-Core Current Transformer

Our FCR and FCM current transformers are now UL Recognized!

We are very pleased to announce that these models are now UL Recognized in compliance with both IEEE C57.13 and CAN/CSA-61869-1 standards!

Our customers frequently request relay class and high-accuracy revenue metering class current transformers as a split-core. Typically, these are solid-core due to the losses that can be introduced from the split. However, it is not always feasible or convenient to install a solid-core, especially in retrofit applications. In 2017, we debuted our cutting-edge FCR series for both relaying and high-accuracy metering applications, while retaining the benefits of a split-core. This led to the development of the FCM series for customers interested in high-accuracy metering but with a smaller form factor than the FCR. Due to the success and increased demand over the years, the product lines have expanded to include a multitude of sizes to fit most applications.

Our Most Popular Model The FCL Flexible Split-Core Current Transformer

The UL Certified FCL flexible split-core current transformer is designed for easy installation on large bus or wire conductors in order to make electrical load surveys or for continuous monitoring of current.

Directional silicon steel is used for the flexible core. Secondary windings are of copper. The entire unit is encapsulated in silicone rubber which protects against moisture, dirt, oil and corona.

Standard outputs for 1A, 5A, 0.333V, and 1V applications.
